The **transitional space** —*transitional space* or *potential space*— is one of Donald Winnicott's most original and fruitful concepts, formulated throughout his clinical work and especially synthesized in *Playing and Reality* (1971).
**Definition**: an intermediate psychic zone between the individual's subjective internal world and the objective external world shared with others. Neither completely fantasy nor completely reality. It is the territory of **play** —when a child uses a stick as a horse, that stick is neither just a stick nor just a horse: it is stick-horse in the transitional space—.
**Transitional objects**: the baby constructs this space through objects it adopts between 6 months and 2 years of age —teddy bear, blanket, pacifier, favorite toy—. These objects are not simply 'things it likes': they are special psychic objects that allow it to tolerate maternal absence by building symbolic continuity between fusion and separation.
**The adult transitional space**: in adult life, this space manifests as the capacity for play —art, creativity, religion, profound science, humor, healthy sexual intimacy—. Everything that is simultaneously real and symbolic lives in the transitional space. Adult psychic health largely depends on the ability to inhabit this space fluidly.
**When it is damaged**: severe early trauma, especially when it includes maternal intrusion or extreme unpredictability, damages the construction of the transitional space. The adult person may have difficulty with creativity, with free imagination, with sexual intimacy without tension, with spirituality without fanaticism. They live in a rigid alternation between fantasy and reality without symbolic mediation.
**Clinical importance**: effective psychotherapy itself creates a transitional space —the consulting room is 'both real and symbolic', the therapist is 'both real and an internal figure'—. It is there that profound transformation can occur. Family Constellations also operate in this space: representatives are 'both real people and symbolic representations' of the client's clan.
Evidence and Contemporary Voices
The concept of 'transitional space' was introduced by Donald W. Winnicott in his theory of child development, describing it as an intermediate area between subjective internal and objective external reality, essential for ego development and creativity through play (Winnicott, 1953). Contemporary research in developmental psychology and relational neuroscience has validated its clinical relevance. For example, Allan Schore's studies at the University of California, Los Angeles (UCLA), integrate transitional space with mother-infant dyadic emotional regulation, showing how early co-regulated interactions facilitate its construction, with evidence of neuroplasticity in the prefrontal cortex (Schore, 2019). Daniel Siegel, at the Mindsight Institute at UCLA, applies the model in interpersonal neurobiology (IPNB) therapy, demonstrating that activating this space in adults promotes brain integration and post-traumatic resilience through mindfulness and relational narratives (Siegel, 2020). Clinical findings from Harvard University indicate that deficits in this early space correlate with adult attachment disorders, measured via scales such as the Adult Attachment Interview (AAI) (Fonagy et al., 2018).

Winnicott's concept: when the caregiver does not respond to the child's authentic self, the child develops an adaptive 'false self'. The true self remains silenced, accessible only in special moments of play or therapy.
